The first furnace door loading and unloading mechanism 3 is used to complete the loading and unloading of the material 7 relative to the transition furnace body 5 on the first furnace door 51 side of the transition furnace body 5, and the second furnace door loading and unloading mechanism 4 is used to complete the loading and unloading of the material 7 equivalent to the kiln 8. In this way, the loading and unloading system can complete the continuous loading and unloading operation of the kiln 8 in a sealed state, that is, the loading and unloading system can be set at the loading end of the kiln 8 as a loading device, and can also be set at the unloading end of the kiln 8 as a unloading device. A set of settings can be used as a loading device and an unloading device, which greatly reduces the R&D and production costs. In addition, the loading and unloading system can also switch the movement direction of the kiln 8 by switching the action sequence to switch the loading and unloading direction of the kiln 8, thereby improving the adaptability;

[0063] The first furnace door material inlet and outlet mechanism 3 is used to move the material 7 into and / or out of the transition furnace body 5 from the opening on the side of the first furnace door 51 when the first furnace door 51 is open and the second furnace door 52 is closed.

When the material 7 is moved into the transition furnace body 5 from the opening on the side of the second furnace door 52, the material 7 in the kiln 8 is transported to the transition furnace body 5 to complete the unloading of the kiln 8. When the material 7 is moved out of the transition furnace body 5 from the opening on the side of the second furnace door 52, the material 7 in the transition furnace body 5 is transported into the kiln 8 to complete the loading of the kiln 8. In the process of completing the movement of the material 7 into and / or out of the transition furnace body 5 from the opening on the side of the second furnace door 52, the first furnace door 51 is in a closed state, thereby ensuring that the kiln 8 is also in a sealed state, and no external gas will flow into the kiln 8. In addition, the second furnace door material inlet and outlet mechanism 4 is arranged on the side of the first furnace door 51, away from the second furnace door 52 and the kiln 8. On the one hand, it is convenient for the configuration, assembly and maintenance of the second furnace door material inlet and outlet mechanism 4. On the other hand, the operation process of the entire second furnace door material inlet and outlet mechanism 4 will not affect the transfer of the material 7 between the transition furnace body 5 and the kiln 8, and will not affect the opening and closing of the second furnace door 52. On the other hand, the linear drive mechanism 421 of the driving part of the second furnace door material inlet and outlet mechanism 4 is located on the outside of the transition furnace body 5, away from the harsh environment of the transition furnace body 5 and the kiln 8, thereby reducing the performance requirements of the linear drive mechanism 421, thereby reducing costs, and increasing the service life of the linear drive mechanism 421.

[0065] The loading and unloading system provided by the utility model has the following beneficial effects:

[0066] 1. The loading and unloading system can be set at the loading end of the kiln 8 as a loading device, and can also be set at the unloading end of the kiln 8 as a unloading device. One set of settings can be used as a loading device and an unloading device, which greatly reduces the R&D and production costs. In addition, the loading and unloading system can also switch the direction of loading and unloading of the kiln 8 by switching the action sequence and adapting to the moving direction of the kiln 8, thereby improving the adaptability;

[0067] 2. By providing a transition furnace body 5 with two furnace doors and a transition furnace loading and unloading device, the kiln 8 can be kept in a sealed state for loading and unloading operations, thereby avoiding the loss of vacuum or leakage of protective gas in the kiln 8 during the loading and unloading operations. When the kiln 8 requires a high temperature environment, heat loss can also be avoided, thereby reducing the energy loss of the kiln 8.

[0068] 3. The setting position of the second furnace door material inlet and outlet mechanism 4, on the one hand, is convenient for the configuration, assembly and maintenance of the second furnace door material inlet and outlet mechanism 4; on the other hand, the operation process of the entire second furnace door material inlet and outlet mechanism 4 will not affect the transfer of the material 7 between the transition furnace body 5 and the kiln 8, and will not affect the opening and closing of the second furnace door 52; on the other hand, the linear drive mechanism 421 of the driving part of the second furnace door material inlet and outlet mechanism 4 is located on the outside of the transition furnace body 5, away from the harsh environment of the transition furnace body 5 and the kiln 8, thereby reducing the performance requirements of the linear drive mechanism 421, thereby reducing costs, and also increasing the service life of the linear drive mechanism 421.

[0069] Fourth, the connecting rod 422 and the sliding hole 511 in the second furnace door feeding and discharging mechanism 4 slide together. On the one hand, the connecting rod 422 can move synchronously with the opening and closing of the first furnace door 51 to maintain the relative position of the two. On the other hand, the sliding hole 511 can also serve as the intermediate support structure of the connecting rod 422, so that the connecting rod 422, which was originally a cantilever structure, becomes a two-point support structure. When the material is pushed and pulled, it is changed to a three-point support structure in which the end of the connecting rod 422 is connected to the material, the middle is slidably connected to the sliding hole 511, and the other end is fixedly connected to the output end of the linear drive mechanism 421, thereby improving the structural stability of the connecting rod 422 in all states, that is, the first furnace door 51 is not only used as a furnace door, but also used as a supporting guide structure for the connecting rod 422. In addition, the connecting rod 422 can also serve as a supplement to the sliding hole 511 to ensure the sealing of the first furnace door 51, ensure the sealing effect of the first furnace door 51, and realize the pushing and pulling of materials when the first furnace door 51 is in a closed state.

[0070] In one of the embodiments, the connecting rod 422 cooperates with the sliding hole 511 in a sliding seal, thereby ensuring the sealing effect of the first furnace door 51 on the transition furnace body 5, and then ensuring the sealing effect inside the transition furnace body 5 when the first furnace door 51 and the second furnace door 52 are both in a closed state, and ensuring the sealing effect of the kiln 8 when the first furnace door 51 is closed and the second furnace door 52 is opened.

[0071] In one of the embodiments, a material embedding mechanism is provided on the material push-pull block 423, and the material embedding mechanism is used to connect the material push-pull block 423 with the material 7, and then pull the material 7 into / out of the transition furnace body 5, that is, the material embedding mechanism is used to complete the detachable connection between the material push-pull block 423 and the material 7, so as to facilitate pulling the material 7 from the kiln 8 into the transition furnace body 5.

[0072] In one embodiment, the material engaging mechanism includes an engaging block 4231 and an engaging block driving mechanism 4232;

[0073] The engaging block 4231 is movably arranged on the material push-pull block 423, and a matching groove 71 is correspondingly arranged on the material 7. The movement of the engaging block 4231 can make the engaging block 4231 embedded in the matching groove 71 to complete the connection between the material push-pull block 423 and the material 7, or make the engaging block 4231 detach from the matching groove 71 to complete the separation between the material push-pull block 423 and the material 7;

[0074] The engaging block driving mechanism 4232 includes a transmission mechanism, a driving rod 42321 and a driving mechanism 42322. The driving mechanism 42322 is arranged on the output end of the linear driving mechanism 421. One end of the driving rod 42321 is connected to the driving mechanism 42322, and the other end of the driving rod 42321 extends into the inner side of the first furnace door 51 through the sliding hole 511 and is connected to the transmission mechanism.

[0075] The driving mechanism 42322 drives the driving rod 42321 to move, and the driving rod 42321 drives the transmission mechanism to drive the engaging block 4231 to move. In this embodiment, the driving mechanism 42322 of the engaging block driving mechanism 4232 is arranged outside the transition furnace body 5, away from the harsh environment of the transition furnace body 5 and the kiln 8, thereby reducing the performance requirements of the driving mechanism 42322, thereby reducing the cost, and also increasing the service life of the driving mechanism 42322.

[0076] In a specific embodiment, the material push-pull block 423 further includes an abutment plate 4233 , which is directly fixed to the end of the connecting rod 422 , so that the abutment plate 4233 can be moved by the linear drive mechanism 421 , thereby pushing the material 7 to move.

[0077] The engaging block 4231 is slidably arranged on the abutment plate 4233 or the connecting rod 422, and the transmission mechanism preferably adopts a gear 42323 and a rack 42324, wherein the rack 42324 is fixed on the upper engaging block 4231, and the gear 42323 is fixed on the driving rod 42321, and the driving mechanism 42322 is a rotary driving mechanism, which is used to drive the driving rod 42321 to rotate, and the driving rod 42321 rotates to drive the gear 42323 to rotate, and the gear 42323 drives the rack 42324 to move linearly, thereby driving the engaging block 4231 to slide linearly, and complete the matching and separation with the material 7. It should be noted that the transmission mechanism can also adopt a transmission mode such as a chain drive or a worm gear, which can be selected according to actual needs.

[0078] In one preferred embodiment, when the engaging block driving mechanism 4232 drives the engaging block 4231 to engage with the matching groove 71 of the material 7, the abutting plate 4233 abuts against the side wall of the material 7. At this time, the abutting plate 4233 and the engaging block 4231 can clamp the material 7, thereby realizing double fixation of the material 7. When the material 7 is heavy and the sliding surface of the moving platform 53 in the transition furnace body 5 is smooth, inertial sliding can be effectively avoided during the pushing and pulling of the material 7, thereby improving the pushing stability.

[0079] In one embodiment, the second furnace door feeding and discharging mechanism 4 further includes a first furnace door opening and closing mechanism 41, and the first furnace door 51 is arranged at the output end of the first furnace door opening and closing mechanism 41;

[0080] The moving direction of the first furnace door opening and closing mechanism 41 is parallel to the moving direction of the linear drive mechanism 421. In this embodiment, the opening and closing direction of the first furnace door 51 is consistent with the moving direction of the connecting rod 422. At this time, the opening and closing action of the first furnace door 51 will not affect the second furnace door feeding and discharging mechanism 4, and the action of the second furnace door feeding and discharging mechanism 4 will not affect the opening and closing of the first furnace door 51. Preferably, the moving directions of the linear drive mechanism 421 and the first furnace door opening and closing mechanism 41 are parallel to the axis of the transition furnace body 5.

[0081] In one embodiment, the loading and unloading system further includes a bracket 1 and a support table 2 arranged on the bracket 1 and moving along the X direction. Preferably, the movement of the support table 2 is automatic rather than manual. Specifically, a first X-direction driving member 21 is arranged on the bracket 1, and an output end of the first X-direction driving member 21 is connected to the support table 2 to drive the support table 2 to move along the X direction.

[0082] The first furnace door opening and closing mechanism 41 and the linear drive mechanism 421 are arranged on the support platform 2, and the first furnace door opening and closing mechanism 41 and the linear drive mechanism 421 both move along the Y direction, that is, the first furnace door opening and closing mechanism 41 and the linear drive mechanism 421 move synchronously with the support platform 2;

[0083] The first furnace door loading and unloading mechanism 3 includes a material carrying platform 31 arranged on the support platform 2 and a material push-pull member 32 that can move on the material carrying platform 31 along the Y direction, wherein the material carrying platform 31 is used to carry the material 7, and the material push-pull member 32 is used to push the material 7 on the material carrying platform 31 into the transition furnace body 5 along the Y direction, or pull the material 7 from the transition furnace body 5 into the material carrying platform 31, thereby completing the loading and unloading of the material 7 at the first furnace door 51 position of the transition furnace body 5;

[0084] The Y direction is parallel to the axis of the transition furnace body 5.
